I confess to being something of a techno-phobe. By that I mean it doesn't take long for detailed engineering and technical discussions to sponsor a brain glaze in me. Some of that is a remnant of my past experience when photography was my "job" and the nature of the work I did was extremely technical and had the end result of ruining the fun of photography for me.
With all that as sort of a disclaimer, I do have a technical question. I understand the principle of diffraction but am not that clear about the point at which it becomes a factor on a lens by lens basis. Generally, I don't stop down much further than f11 and figure I'm safe. But is there more I should know? Is the effect of diffraction different depending on the lens design? The focal length? Is it even an issue that needs to be considered?
Do you factor diffraction into your decision-making process when shooting?
